Add FPGA_TARGET=ECP5-EVN make option for synthesis build

This allows these targets
  FPGA_TARGET=ORANGE-CRAB make microwatt.bit
  FPGA_TARGET=ECP5-EVN make microwatt.bit
Default is ORANGE-CRAB as before

ECP5-EVN is tested on real hardware. The console only works at 38400 so
needs this in console.c and a recompile of hello_world to work:

  -#define UART_FREQ 115200
  +#define UART_FREQ 38400

With this 'FPGA_TARGET=ECP5-EVN make prog' works on the ECP5 dev board.
